Background
Here is my full list of publications. I am currently in the process of making these available in PDF form; in the meantime please email me if you would like an electronic copy of any of the papers listed.
For quick and easy calculations of the vertical bearing capacity of strip and circular foundations, I have written the popular free software ABC - Analysis of Bearing Capacity. A new version, featuring calculations of the consistent velocity field and extended stress field, is undergoing final testing and will be available for download soon.
You may prefer a traditional approach to bearing capacity calculations based on superposition, which is conservative provided the correct bearing capacity factors are used. Definitive exact values of Nc, Nq and Ngamma are available for download in Excel or PDF format. Note that many commonly used formulae for Ngamma (e.g. Vesic, Eurocode 7) give results that are too high.
The slides from my lecture "Exact bearing capacity calculations using the method of characteristics" can be downloaded from here (2.7 MB PowerPoint file). You can also view the accompanying paper.
